Well, I don't know if this is as optimized as it could be, since I'm more of a PO than a TO, but I'm rather proud of this gunslinger:

Attack pattern and damage
[spoiler]AB:20+6+2-2-1= 25
Enough to hit pretty much anyone except Darth Vader on an average roll.
If you got a Inspiring Noble in your team, it gets even better.
Dirty Fighting + Greater Devastating Attack: Targets Threshold is at -12 against these attacks.
Specific Equipment:
2 Heavy Blaster Pistols with the upgrade that gives you -1 to hit but +1 damage per die.
Damage First Shot:
3d8+10+2+4+3+(2)
3d8 base damage.
10 heroic.
2 is Weapon Spec.
4 is Trusty Sidearm
3 is the upgrade
(2) is Ruthless if the other damage is enough to break threshold.
Second:
4d8+10+2+4+4+4
Savage Attack kicks in after the first hit, increase damage by 1 die. Upgrade also then increase by 1 point.
Ruthless stack, so now it provides 4 points.
Third:
5d8+10+2+4+5+6
Attack Combo (ranged) kicks in if the first two attacks hit. Add another die, the extra point from the upgrade and Ruthless again.
Fourth:
5d8+10+2+4+5+8
Ruthless.
17d8+40+8+16+17+20.
That average of 177,5 damage on a single target.
[/spoiler]
Sure, the target could have a monstrous threshold or your attacks could miss or not enough hit to activate some combinations.
But I still think it's good.
